I'm trying to install a new 'user' component into Cocoon 2 but I'm
hitting a problem which I can't seem to get a handle on:
Basically, I'm getting a the following stack dump:

My new DatabaseAccessGenerator (generator) is composable and uses the
given manager to lookup the new component called DatabaseAccessManager.
This component is defined in my my.roles file:
> <?xml version="1.0"?>
> <role-list>
> <role name="com.adolos.cocoon.util.DatabaseAccessManager"
> shorthand="database-access-manager"
> default-class="com.adolos.cocoon.util.DatabaseAccessManager"/>
> </role-list>
The my.roles file is referenced in my cocoon.xconf file as:
> <cocoon version="2.0" user-roles="/WEB-INF/my.roles">
This appears to be being accessed, as prior to putting in the preceding
forward-slash this reference threw a runtime error as well.
The cocoon.xconf file also has an entry for the component like this (I'm
not sure if this is really necessary):
> <database-access-manager
> class="com.adolos.cocoon.util.DatabaseAccessManager"
> logger="core.database.access" />
I have some logging in place and I know that the compose and configure
methods of my DatabaseAccessManager component are called prior to any
attempt to use the component.
But, when my DatabaseAccessGenerator attempts to lookup the component it
throws the 'Could not find component' exception listed above (top).
I've checked and double-checked that the role names match up throughout.
Any thoughts?
P.S. I've produced plenty of working generators in the past, but this is
my first independent component so don't underestimate my ability to do
something stupid!
